background-attachment property

Browser support:

Specifies whether the background-image should scroll with the contents of the object or not.

With this property you have control over how the background image behaves when the contents of the element are scrolled (stays in a fixed position, or scrolls with the contents, as it normally does).

When a fixed value is used with background-position, the position is relative to the client window of the browser. For that reason, a fixed value is used for the body tag most of the cases.

JavaScript page for this property: backgroundAttachment. You can find other example(s) there.

Possible values:

One of the following values:

fixed

Background image stays fixed.

inherit

Takes the value of this property from the computed style of the parent element.

scroll

Default. Background image scrolls with the contents of the object.

Default: scroll.
